All chipsets from AR7100 up to QCA9563 have three dedicated chipselect lines for the integrated SPI controller. Remove the number of chipselects from the platform data, as there is no need to manually set this to a different value. Signed-off-by: David Bauer <mail@david-bauer.net>

lines for the integrated SPI controller. Remove the number of

chipselects from the platform data, as there is no need to manually set
